CASH-REGISTER.

QPECIFICATION forming part of Letters Patent No. 449,395, dated March 31, 1891. Application filed October 21, 1890. Serial No, 368,861. (No model.)

To ctZZ whom it may CUYLCGI'IL.

Be it known that I, JOHN II. AHRENS, of Brooklyn, in the county of Kings, in the State of New York, a citizen of the United States, have invented certain new and useful Improvements in Gash-Registers and Adding- Machines, of which the following is a specification.

This invention relatesto improvements in that class of machines that are used for registering and adding amounts.

The object of my invention is to provide a machine of this kind which is simple in construction, reliable and quick in operation, and which automatically opens the money drawer as soon as the machine is used to count, the closing of the drawer bringing the counting-hands back to the original position.

The invention consists in the combination, with a casing, of a drawer, a springfor throwing the drawer outward, an adding mechanism in the casing, and a locking-lever operated by the addingmechanism and servingto lock the drawer in place.

The invention also consistsin the construction and combination of parts and details, which will be fullydcscribed hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure l is a front elevation of my improved cash registering and adding machine. Fig. 2 is a vertical longitudinal sectional view on the line 2 of Fig. i. Fig.3 is avertioal longitudinal sectional view on the line 3 3 of Fig. a. Fig. at is a horizontal sectional plan view on the line a at of Fig. 2. Fig. 5 is a side view of the mechanism, the casing being shown in vertical transverse sectional view, parts being broken out; and Fig.6 is a horizontal sectional view on the line (3 6 of Fig. 5.

Similar letters of reference indicate corresponding parts.

The counting mechanism is contained in a casing A, secured on a hollow base A, c011- taining a drawer A provided at the front with a suitable handle A To the innersurface of the rear wall of the hollow base A a spring A is secured, which bears against the rear edge of the bottom of the drawer A and throws said drawer outward. The mechanism is secured to two standards 13 B, fastened on the base. In the front standard B the sleeve G is mounted to turn, and through said sleeve 0 the arbor C passes, the rear end of which projects from the back of the rear standard B. A handle or pointerD, having a handle-knob d, is secured to the front end of the arbor O, and a like but longer hand or pointer I), having a handle-knob (Z, is secured to the front end of the sleeve 0. A spiral spring E has one end secured to the sleeve 0 and its other end secured to a pin 0, fastened on an arm 13 of the front standard B. In a like manner a spiral spring E is secured to the rear end of the arbor O, the other end of said spiral spring E being secured to the arm of the rear standard B in the same manner as the end of the spring E is secured to the arm of the front standard B.

On the sleeve 0 a disk F is loosely mounted, and on its face is divided into one hundred parts along the circumference, which parts or subdivisions are nu mberod. A s prin gpawl f on the disk Fengages a toothed wheel G, fixed on the sleeve (1, and to said toothed wheel G another toothed wheel 9 is fixed, the teeth of the two wheels projecting in opposite directions. To said wheel g an arm G is secured, the end of which can strike against a stop or lug B on the end of the arm 13 on the front standard 13. 4

On the arbor O a disk F is loosely mounted, which is provided on its face along the rim with fifty subdivisions, and aspring-pawl f on said disk engages a toothed wheel G, fixed on the arbor O, and to said toothed wheel G a toothed wheel g is fastened, the teeth projectingin opposite directions. There are as many teeth on the wheels Go as there are subdivisions on the disk F and as many teeth on the wheels G g as there are subdivisions on the disk F. To the wheel g is fastened an arm G that is adapted to strike against a stop-lug G on a standard G of the machine-frame. To the back of the disk F is fastened a tooth or lug II, that is adapted to engage the teeth of a wheel 71, having twenty teeth, each of which is numbered, said toothed wheel h having a fixed lug 7t, adapted to engage the toothed wheel 7L2, having twenty teeth. Said wheels h and 71, are mounted 011 an arm B of the front. standard B. The disk F is provided with a lug or tooth H, adapted to engage the teeth of a wheel H having twenty teeth, said wheel H being fixed on a suitable shaft mounted in the'st'andards B and B. Springpawlsh h, and If engage the teeth of the wheels 71,11 and 71 respectively. The pointers J and J are arranged to point to the numerals on the disks F and F, respectively, and the pointers J J and J 4 are arranged to point to the subdivisions on the wheels 71', h, and 11 respectively. A spring-pawl leverK, pivoted to the front standard R, has its upper toothed end so arranged that the same can engage the teeth on the toothed wheel g in front of the disk F. The lower ends of said levers project into the hollow base andare adapted to be acted upon by the two cam-lugs L and L, projecting upward from the bottom of the drawer A On the inner end of the sleeve G a disk M is mounted, and adjacent to the same a like disk M of the same size is fixed on the arbor 0, both of said disks being provided with the notches N, which are tapered at one side. Into said notches N the tooth O is adapted to snap, which projects from the upper end of the locking-lever P, the lower endof which lever is adapted to engage the shoulder Q on a cam-lug R, extending upward from the bottom of the drawer. A suitable spring S, acting on the upper end of the lever P, keeps the tooth on the upper end of said lever in -contact with the edges of both disks M and M. "he front of the casing A is provided with a dial having the two circles T and U, of which the former is divided into fifty parts and the latter into one hundred, the said circles being so arranged that the end of the pointer D travels over the circle T and the end of the pointer D travels over the circle U. Each subdivision of the circles T U is provided with an aperture an, adapted to receive a check-pin n, fastened to a chain or cord 0, which in turn is secured to the side of the casing. The lower parts of the circles T U of the dial are provided with a hinged section WV on the front of the casing. By raising said wing or lower hinged section W the numbers indicated by the pointers J, J, J J and J on the disks F F and wheels 72, b and H can be examined. The wing W is provided with a lock V. The large hand or pointer D is used to register cents and the smaller one D is used to register dollars.

The operation is as follows: Both pointers or hands D D are at zero on the circles T U, and the pointers J, J, J J and J point to zero on the disks F F and the wheels W, h, and H The drawer is within the casing and is locked in place by the locking-lever P, the lower end of which engages the shoulder Q on the cam-lug R, fixed in the drawer. The drawer cannot be pulled out when thus locked. If a certain amount of money is to be deposited-for example, twenty-three c'entsthe operator places the pin 71. into the aperture m in the subdivision 23 on the outer circle U, and then the hand or pointer D is moved in coins in the same.

the direction of the arrow 00, Fig. 1, until it strikes against the pin it in the aperture m of the subdivision 23 on the outer circle U, where it remains, thus indicating that the attendant has registered twenty-three cents. As soon as the hand or pointer D is turned in the direction indicated the corresponding disk M is rotated in the direction of the arrow m, Fig. 1, and presses the upper end of the locking-lever P outward-that is, to the rightwhereby the lower end of the lever is moved to the left and is disengaged from the shoulder Q on the cam-lug R, thus permitting the spring A to throw the drawer outward, so as to permit the attendant to deposit the turned by the hand D, and as it engages the pawl f the disk F is rotated a distance corresponding to the distance that the hand or pointer D is turned. The pawl-lever K, engaging the toothed wheel g, locks the several parts in place. After the money has been deposited the drawer is pushed inward, and as the cam-lug L strikes the lower end of the pawl-lever Kit moves the lower end of the same to the left, thereby moving the upper end to the right and disengaging it from the toothed wheel g, permitting the spring E, which was brought into greater tension by turning the hand D in the direction of the arrow or, to throw the sleeveC, toothed wheels G g, and the pointer D back in the inverse direction of the arrow '00 until the pointer D is at zero of the circle U again. The arm G strikes against the stop-lug B thereby preventing the spring from throwing the hand D farther in the inverse direction of the arrow 0: than the zero of the circle U. The disk F remains in the position into which it was brought by the turning of the hand D Q in the direction of the arrow to. If another amount-for example, eighteen centsis to be deposited, the above operation is repeated. As soon as the hand D is turned, and if it is turned only the distance of one subdivision, corresponding to one cent, the drawer is released and thrown outward, and as soon as the drawer is pushed back the toothed wheel 9 is released and the hand brought back into position by the action of the spring E. If dollars are to be recorded, the pin 12 is placed into one of the apertures m of the circle T, and the smaller hand D is turned in the manner described, and in the same way releases the drawer, as the wheel M now acts on the locking-lever P, and when the drawer is pushed back the cam-lug L, acting on the lever K, disengages said lever from the toothed wheel 9, permitting the spring E to throw the hand D back into its original position. Every time the disk F makes one complete revolution, corresponding to one dollar, the wheel his rotated the distance of one tooth, and every time the wheel it makes one complete revolution, corresponding to twenty dollars, its lug it rotates the wheel h2 the distance of one tooth, corresponding to twenty The toothed wheel G is dollars. Every time the disk F makes one complete revolution, corresponding to fifty dollars, the wheel H is rotated one tooth, and so on. The contents of the drawer must correspond to the amount indicated by the pointers J, J, J J, and J on the disks F and F and the counting-wheels h, 72,2, and 11 To verify the account, the wing is unlocked and raised, and the positions of the pointers J, J, J J and J 4 of the several wheels are noted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a cash registering and adding machine, the combination, with a casing, of a drawer, two independent concentric addingdisks, means for rotating them independently of each other, an independent lockingdisk connected with each adding-disk, a lockinglever engaging both of said locking-disks, and a projection on the drawer engaging said locking-levers, substantially as set forth.

2. In a cash registering and adding machine, the combination, with two independent concentric adding disks, of independent means for rotating them, a toothed wheel connected with each disk, a lever engaging said toothed wheel, and a drawer in the casing and cam projections in the drawer, said cam projections being adapted to act 011 the pawllevers, substantially as set forth.

3. In a cash registering and adding machine, the combination, with two independent concentric adding-disks, of a locking-disk connected with each adding-disk, a lockinglever adapted to engage both adding-disks, a drawer in the casing supporting the adding mechanism, a shouldered lug adapted to engage the locking-lever, a toothed wheel connected with each adding-disk, a pawl-lever engaging each toothed wheel, and independent cam projections in the drawer adapted to act on said pawl-1evers, substantially as set forth.
